Characteristics of Steel Structure Engineering

Steel Structure Engineering Atlas

Although China had outstanding achievements in iron structure in the early stage, due to the constraints of over 2000 years of feudal system and underdeveloped science, it remained at the level of iron buildings for a long time. It was not until the late 19th century that China began to use modern steel structures. After the establishment of the People's Republic of China, the application of steel structures has made great progress, far surpassing the past in terms of quantity and quality. I have achieved a high level of skills in design, manufacturing, and installation, and have mastered the design and construction skills of various disorderly buildings. I have produced many large-scale and disorderly steel structure factories, large-span steel structure civil construction, and railway bridges across the country, including the steel roof truss of the Great Hall of the People in China, and the steel grid truss of sports stadiums in Beijing and Shanghai, The three hinge steel arch of the Shaanxi Qin Shi Huang Soldier and Horse Mercenary Exhibition Hall and the Bird's Nest in Beijing.

Seismic resistance: The roofs of low-rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After sealing the structural panels and gypsum boards, the light steel components form a very sturdy "plate rib structure system". This structural system has stronger seismic resistance and ability to resist horizontal loads, and is suitable for areas with seismic intensity of 8 degrees or above.

Wind resistance: The construction of steel structures has the advantages of light weight, high strength, good overall rigidity, and strong resistance to deformation. The self weight of the building is only one-fifth of that of the brick concrete structure, which can withstand hurricanes of 70 meters per second and effectively protect life and property.

Durability: All light steel residential structures are composed of cold-formed thin-walled steel component systems, and the steel ribs are made of super corrosion-resistant high-strength cold-rolled galvanized sheets, effectively avoiding the impact of steel plate corrosion during construction and use, and increasing the service life of light steel components. The structural life can reach 100 years.

Insulation: The selected insulation materials are mainly made of fiberglass cotton, which has a good insulation effect. The insulation board used for the exterior wall effectively avoids the phenomenon of "cold bridge" on the wall, achieving better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to that of a 1m thick brick wall.

Sound insulation: The sound insulation effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are all made of insulated glass, which has good sound insulation effect and can achieve a sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can have a sound insulation effect of up to 60 decibels.

Health: Dry construction, reducing environmental pollution caused by waste, 100% recycling of steel structure materials for houses, and most of other supporting materials, which is in line with current environmental awareness; All materials are green building materials that meet the requirements of the ecological environment and are beneficial to health.
